IMPROVED APPARATUS FOR THE DISCHARGE-AND PREPARATION 0F GRANULARORE ANDCOALrAND' SIMILAR MATERIALS.

Be it known that-I, PETER OsTERsrEY, of

and useful Improvements in Apparatus for the Discharge and Preparationof Granular Ore, Minerals, Goal, and Similar Materials; and I do herebydeclare the following to be a full and true description thereof,reference heilig had to the accom panying'drawings, and tothe letters ofreference markedthereon. y

This invention relates, principally, to the manner of discharge andseparation of granuis in the construction of the discharging-gate foradjustment in laccordance with the nature of the ore or coal; secondly,said invention relates to thegeneral construction, arrangement,andoperation of the apparatus for preparation and-separation of the heavyand light components of ore, so as to insure a continuous and economicale'ect without undue liability of clogging or choking of parts, or ofinterruption in the operation ofthe apparatus, either from clogging orchoking, or from variations in the size or quality of the granules ofore 0r coal.

To enable those herein skilled to make and use my said improvements, Iwill now more Figure l as a side view, to Fig. 2 as a sectionalelevation at the line w y, to Fig. 3 as a plan, and to Figs. 4 and 5 asdetail section and elevation, respectively, of the discharging-gate andconnecting parts. y

In its more usual form, my said machine for separating ore and coalconsists of' a strong wooden or iron frame, A, within which are inclosedtwo or more hydraulic jigger or separator machines, BB. Each of saidmachines has a proper sieve, C or C', for receiving the granulatedstuii'. Said sieve rests upon. a proper grating over a well, which, atits base, connects with a water-chamber, D or D', in which a plungerplays, to cause the water to surge up above the sieve, and thus carryupwardly the particles of ore or coal with the ad mixtures andimpurities, and then allow the masses to Settle, as in accordance withtheir respective gravities in the general mannerusual'insimilarmachines.

The plungers Ev E'will usually be of'fwood, v

arranged with proper valves to permit the pas- .sage of water back tothe waterchamberin e c with proper crank-arms, which aresecured Y uponthe shaft F, resting upon the framework A. Said shaft has :a lever, f,which, bya link, f', is Vconnected .with the-lever g upon theshaft G.This shaft is operated -froml the powershaft H by the crank andlink-connection, as indicated in Figs. l and 3. To regulatethepiston-stroke the leversf andg are arranged with holes, which allow theadjustment of the link f at different heights above'the [shafts F andG.v

The ore, coal, or other material `may betreceived directly from thecrushers into faifeedhopper, I, from which it passes' tolthe sieve C,being regulated in its inilow by a suitable slide, c. The water willthen achieve the separation, as above described, and the lighter stu,usually dross, will be swept over the top of the gate-box K, while theheavier ore will deposit near the top of the sieve G to be drawn offthrough the gate K1 and tube L at the discharge M.

v In order to regulate the discharge ot the stuff at the gate K1, as inthe nature of this invention, l have arranged within the box K the saidgate, as more especially indicated in Figs. 4 and 5. The front side ofthe box has the inlet openingv or openings k. .To the ends of said boxis pivoted the gate K1, the front face whereof is rounded cylindricallyto iit the contact-surface of the gate box. Said face of the gate isarranged with V- shaped recesses k1, the apex of the indentations beingabove, so that as the gate is raised the effluxopenings formed by saidrecesses are increased. To 'adjust the position of said gate I connectthe same, by a suitable pivot, with the link and screw-rod k2, which israised by turning a hand wheel and nut, generally as shown in Figs. land 2. Instead of said hand-wheel and screw-rod, the adjustment of thegate may `undue accumulation of stuff at the gate, so

as to clog the discharge, such accumulation will be readily removed' byraising the gate to a proper height to cause the Water and stuff to flowoutat the enlarged vent. 1f the ore is poor in metal the gate maybeclosed to await a proper accumulation of metal at the sieve before adischarge is made. l

The lighter stuft` which is carried over the bridge or box K willusually be carried to a second sieve, C', being here subjected to a'second separation, whereby the dross or light stud' is discharged overthe second gate-box K2 into a trough, N. The heavier mass passes throughthe gate in said box, (as before described for the passage of the gateK1,) and through a proper conduit to 'the discharge N', similarly formedto the discharge M. The discharge-outlets will be closed by proper plugsor valves n and m, respectively, and the general arrangement of saiddischarges may be such as is indicated in the several figures, l, 2, and3.

From the dischargespouts vN and M the granular mass is dropped upon asieve, O, in a proper trough, O', to be utilized in the proper manner.'lhe Water passes out of said trough O' by a conduit, o.

In order that the well and water chamber may be readily cleansed, thesewill have hopof grains varying in neness.

4 per-bottoms leading to conical or other drainspouts P. The openingsthereof are over the conduit '0, and are controlled by valves operatedby rods and hand-Wheels p.

The Water as needed in the said operations Will be delivered to thewells and Water chambers by a suitable supply-pipe.

In the application of my apparatus for the Washing and screening-ofcoal, the coal particles, bein'glighter than the usual admixtures, (suchas iron pyrites, shale, and others,) will go over the bridge top of thegate-box; but, by the use of a number of separating devices, the coalitself may be separated into masses The ores (or admixtures whenscreening coal) whichv are specifically heaviest will, as abovedescribed, ind a ready discharge, either continuously or intermittently,as may be deemed proper, the said discharge (as well as theentireprocess) being achieved with a very economical eX- penditure ofpower or water.

Having thus fully described my invention, what I claim is 1. Thegate-box K and its gate K1, the latter arranged with A-recesses, andadjusted by a rod, k1, and hand wheel or similar device, substantiallyas set forth.

2. The arrangement of the hydraulic separator or jigger with severalwells, each of which has its sieve and gate-box and adjustable gate inconnection with each other, so as to separate the orc, coal, or othermatter into granules of varyingl fineness, substantially as set forth.
